- add additional kernel boot params for i915 where needed:
- adds : drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0 ( to permit kexec into vesa fb of kexec'ed kernel for i915 driven gpus without framebuffer compression, leaking smem fbdev address for kexec to pickup )
The calculations outlined at https://github.com/osresearch/heads/pull/1282#discussion_r1072473677
Sums to having 'ifdtool -f layout.txt ifd_shrinked.bin && cat layout.txt'
The example for T440p:
00000000:00000fff fd
00021000:00bfffff bios
00003000:00020fff me
00001000:00002fff gbe
Here: 00bfffff-00021000=BDEFFF
Which is exact result of @rbeslow's calculations.
There is an issue on haswell, maybe because of car, maybe because of non native memory init blob.
But this is not the case for xx20/xx30 boards.
This makes configs much less dependent on directory layout.
As of this commit the following variables are supported:
* @BOARD_BUILD_DIR@ - absolute path under build/
* @BLOB_DIR@ - absolute path to blobs/

- xx30 legacy boards (x230, x230-flash, t430, t430-flash) now rely also on coreboot 4.13
- DOWNSIDE: x230 and t430 legacy boards now rely on WHIPTAIL (NOT FBWhiptail) to have enough space to fit under 7mb)
- xx20 boards moved to 4.13 (no need of xx20-flash boards here since single SPI boards with 7.5mb useable since blobs scripts are required)
- DOWNSIDE: all xx20 boards now have dropbear deactivated, while still having ethernet driver in.
- qemu-coreboot and qemu-coreboot-fbwhiptail switched to coreboot 4.13 WITHOUT TPM SUPPORT (with cryptsetup 2.x support)
- DOWNSIDE:
- coreboot-qemu board CBFS_SIZE=0x700000 -> 0x750000
- coreboot-qemu-fbwhiptail CBFS_SIZE=0x750000 -> 0x780000
- CircleCi build recipe removes 4.8.1 boards altogether
- KGPE-D16 workstation is used as new base build to save workspace layer (we removed one workspace layer)
- Removing one workspace layer will save approx 2 hours of build time on fresh builds
- Removing one coreboot version will save us approx 2 hours of build time on fresh builds
- KGPE-D16 will stay to coreboot 4.11 until forward notice.
- All other board configs SHOULD be built on latest coreboot versions
- all: coreboot NO_POST for all boards
- all: coreboot NO_GFX_INIT (linux payload does the graphic init)
- all: coreboot TPM_MEASURED_BOOT (no more patches under Heads for measured boot)
- all: coreboot DRIVERS_PS2_KEYBOARD (fixes no keyboard on soft reboot and potentially xx30t xx20t fix for random raw keyboard (to be tested)
- all: coreboot removal of DEFAULT_CONSOLE_LOGLEVEL_5 under some boards
- all: coreboot removal of "loglevel=3" under some linux command line options booting Heads kernel
- all: coreboot removal of DEBUG_SMM_RELOCATION (unneeded)
- all: coreboot INCLUDE_CONFIG_FILE and COLLECT_TIMESTAMPS for all boards
- all: coreboot CONSOLE_SERIAL present on all boards
- all: coreboot add VBT
- all: board configs switch to cryptsetup2
xx20 hotp-maximized boards:
- removal of dropbear (not enough space to have htop + dropbear)
txx0 boards coreboot:
- USE_OPTION_TABLE and STATIC_OPTION_TABLE added (todo: check T430 boards optimization and find issue/PR and ammend this commit)
